Re: Daikin mono bloc low temperature

Hi

we have 11 rads of one Daikin monobloc of 16kw 3 phase our outdoor temp at night is 12 degrees with day time of 24 when we run the system at 40 degrees from controller works great when this is on 55 degrees the system shuts off check for and air all ok, water ok hope this helps uand thanks for your time

Re: Daikin mono bloc low temperature

Diificult to second guess this one. There are a few possibilities that it could be and I would not want to jump to an incorrect conclusion.
As it would appear to possibly be time related, check that there are no strange timer settings invoked.

Re: Daikin mono bloc low temperature

It could be reduced water flow or potentially an air bubble causing reduced flow. if the system works fine when set at 40degC, there may be insufficient heat transfer at the elevated temperature. There should be a minimum deltaT of 5degC. 55degc at right at the top end of the capability of the unit. Possibly the heat loss of the system and building prevents the system from achieving 55degc and the unit may be cutting out on high compressor temperature. This would not necessarily indicate a fault code as the system would eventually stop and then restart after a time period.
